Description

Double-truss bracket structure of large pipeline

Technical Field

The utility model relates to the field of building construction, in particular to a double-truss bracket for a large pipeline.

Background

The design and the form selection of the pipeline support and hanger bracket structure are an important component part in the pipeline system design, besides supporting the weight of the pipeline, the special pipe bracket can balance the acting force of the pipeline system, limit the displacement of the pipeline and absorb vibration, and when the pipeline system is designed, the pipe bracket with reasonable structure is properly selected and arranged, so that the stress distribution of the pipeline and the acting force on the pipe bracket can be improved, the safe operation of the pipeline system is ensured, and the service life of the pipeline system is prolonged.

The electromechanical pipeline support is a structural member for overhead laying electromechanical pipeline support on the ground, and the pipeline support can be used in any place where a pipeline is laid, and is also called a pipeline support, a pipeline part and the like. A pipe expansion bolt type bracket is a form of bracket mounting in which the bracket is fixed to a wall, roof, and floor by expansion bolts. Modern buildings are required to be convenient to maintain and attractive in appearance for electromechanical exposed pipelines, so that a plurality of buildings are arranged by arranging the pipelines in a line and are supported by a pair of supports.

At present, a plurality of large-scale office buildings and large-scale comprehensive commercial establishments exist, and due to the overlarge use area, various pipelines are various, such as electromechanical pipelines, air-conditioning pipelines or sewage pipelines, and the like, main pipelines of the large-scale office buildings and large-scale comprehensive commercial establishments are generally gathered on an underground equipment layer, for example, the main pipelines are arranged at the top of the underground garage through supporting and hanging frames and finally reach the space between professional equipment. One end of a pull rod is fixed at the positions of a top wall, a wall, the side wall, the bottom surface and the like of a lintel by adopting expansion bolts, the other end of the pull rod is connected with angle steel or channel steel, the channel steel is used as a support for supporting the pipeline to bear the weight of the pipeline, and as shown in fig. 1 and 2, the prior art hanger mainly comprises a steel beam 1, an angle channel steel 2, a U-shaped clamp 3, a full-thread suspender 4 and a nut-section steel gasket-section steel spring nut 5 or is connected with an embedded nut or an expansion anchor bolt 6 at the upper part of the full-thread suspender 4, and is connected with a punching angle steel 7 at the lower part through a nut washer 8. However, some large pipes such as main air conditioner pipes, main sewage pipes with a diameter of more than about 300mm, or electromechanical pipes with a cross-sectional area similar to that of the main air conditioner pipes have to increase the density of the hangers appropriately or to enhance the strength and carrying capacity of each hanger due to the large weight per unit volume. Otherwise, if the bearing capacity of the support member is not enough or the connection strength between the support member and the wall and the roof is not enough, the outlet pipeline is inevitably dropped, so that the loss of property of a merchant or a customer, and even serious accidents of casualties of outlet personnel are caused. In terms of increasing the bearing capacity of each supporting hanger, the size and specification of supporting pieces such as angle steel, channel steel and pull rods are mostly increased, or single-truss supporting is changed into double-truss supporting, even multiple-truss supporting and the like. However, because the top of the underground equipment layer is limited by numerous pipelines and extremely limited installation space of the supporting and hanging frames, when the support cannot be adopted and the specification of the support piece is limited to be increased, the requirements can be met by adopting different specifications, sizes and different forms according to the specific situation of field installation according to local conditions. For example, the hanging frame of a pipeline at a certain place just catches up with the cross beam, the cross beam can affect the installation of the hanging frame, and taking a double hanging frame as an example, the hanging frame structure and the connection form with the roof and the strong connection form are specially designed according to the actual situation so as to ensure the requirement of pipeline support at the place.
